Carrying a Heavy Load
Articulated haul trucks meet the heavy-hauling needs of aggregates operations, but they also offer something more — maneuverability.

More horsepower/ergonomic design
Case Construction Equipment says its new 327B and 330B articulated trucks feature more horsepower, an ergonomically designed cab, and a variety of service and maintenance features. The Tier III-certified, electronically controlled 10-liter engines use unit injectors to increase the pressure of fuel entering each cylinder and feature a variable geometry turbocharger to provide an optimized air-to-fuel mixture. The fully adjustable, ergonomic cab features a long, sloping hood design and a floor-to-ceiling glass door for great visibility.
K-Tec Earthmovers Inc. says its new articulated dump truck (ADT) series is compatible with its scraper’s motor unit and allows a contractor to switch a six-wheel drive ADT between material hauler and scraper power unit in a matter of hours, depending on the model. The truck offers many advantages, including high speeds, a smooth ride, fast hydraulics, tight turning radius, perfect weight balance on all three pulling axles, better floatation than motor scrapers, and accommodation for lesser-skilled operators.
Reduced noise levels
Komatsu America Corp. says its HM400-2 articulated dump truck meets EPA Tier III emission regulations and features a hydro-pneumatic front and rear suspension, two-stage lift cylinders, reliable wet multiple-disc brake retarder, and maintenance-free oscillating hitch. The truck also has reduced ambient noise levels and lead-free radiators, as well as a 29.2-cubic-yard capacity and loading height of 9 feet, 9 inches. The company’s Komtrax technology allows machine operating information — hour meter, location, cautions, maintenance alerts, and more — to be sent to a secure Web site via wireless technology.
